The web-hosting or server is much like the space that you rent out to have your business in. It's merely the space itself. Without the hosting services, you won't have a place for your files to reside, so your domain would then become like a disconnected phone number in the phone directory, and your site files would have nowhere to stay.
great passive solar design- I would plant row of deciduous trees in front of glass so that in the winter that could act as a giant trombe wall but be shaded to keep it cool in the summer. Trees that max out at 2 stories would allow south face 3rd level roof to accommodate panels!
